Abstract
Description
Die Erfindung betrifft eine Vorrichtung in Rundbauweise zum Klassieren oder Sortieren von Gut, auch Siebmaschine genannt, insbesondere eine Taumelsiebmaschine. Eine solche Siebmaschine ist zum Beispiel bekanntgeworden aus dem Prospekt "Taumelsiebmaschinen" der Anmelderin vom April 1998. Dabei wird unter "Klassieren" ein Trennen nach Korngrößen verstanden und unter "Sortieren" ein Trennen nach Stoffarten. Die Erfindung ist grundsätzlich bei beiden Verfahrensarten anwendbar. Der Einfachheit halber soll aber im folgenden nur der Begriff "Klassieren" verwendet werden.The invention relates to a circular construction device for classifying or Sorting goods, also called screening machines, especially one Tumbler screening machine. Such a screening machine is for example became known from the prospectus "tumble screening machines" of the applicant from April 1998. "Classification" is a separation by grain size understood and under "sorting" a separation by substance types. The invention is basically applicable to both types of procedure. The simplicity for the sake of convenience, however, only the term "classifying" should be used in the following.
Vorrichtungen dieser Art werden in sehr vielen Industriezweigen eingesetzt. Nur beispielsweise seien die Lebensmittelindustrie, die Spanplattenindustrie die chemische Industrie genannt. Die Vorrichtungen dienen dabei zum Zerlegen eines fließfähigen oder schuttfähigen Gutes in fester oder flüsssiger Form, beispielsweise in Gestalt einer Suspension, in einzelne Bestandteile. Ein möglicher Zweck einer solchen Vorrichtung besteht beispielsweise darin, ein körniges Gut in verschiedene Fraktionen unterschiedlicher Korngrößen zu zerlegen. Ein weiterer Anwendungsfall ist das Abtrennen von Verunreinigungen aus einem Gut.Devices of this type are used in very many branches of industry. The food industry and the chipboard industry are just examples called the chemical industry. The devices are used for Disassembly of a flowable or pourable material into solid or liquid Form, for example in the form of a suspension, in individual components. On possible purpose of such a device is, for example, a granular material in different fractions of different grain sizes disassemble. Another application is the separation of Impurities from a good.
Eine Vorrichtung der genannten Art umfaßt dabei ein Gehäuse, ferner wenigstens ein Klassiersieb, wenigstens einen Einlaß für das zu klassierende Gut, wenigstens einen Auslaß für den Gutstoff und wenigstens einen Auslaß für den Rückstand.A device of the type mentioned includes a housing, further at least one classifying screen, at least one inlet for the classifying Well, at least one outlet for the accept and at least one outlet for the backlog.
Soll ein Gut in zwei oder mehrere Fraktionen zerlegt werden, so benötigt man hierzu eine Siebmaschine mit einer entsprechenden Anzahl von Siebdecks. Diese sind im allgemeinen übereinander angeordnet. Das Gut wird dabei zunächst auf das obere Deck aufgegeben. Hierbei entsteht eine erste Fraktion, die durch einen ersten Gutstoffauslaß aus dem Gehäuse der Siebmaschine ausgeschleust wird. Diese erste Fraktion weist relativ große Partikel auf. Das somit ein erstes Mal gesiebte, verbleibende Gut, das durch den ersten Siebkörper hindurchgetreten ist, gelangt sodann zu einem zweiten Siebdeck. Hier wird eine zweite Fraktion mit Partikeln etwas geringerer Größe abgetrennt. Die einzelnen Siebdecks sind übereinander angeordnet. Die Siebmaschine hat daher eine gewisse vertikale Erstreckung, die eine entsprechende Raumhöhe der Betriebsgebäude erforderlich macht. Diese ist nicht immer vorhanden.If a good is to be broken down into two or more fractions, one needs a screening machine with a corresponding number of screening decks. These are generally arranged one above the other. The good will be there first abandoned on the upper deck. This creates a first Fraction, which through a first Gutstoffauslass from the housing of the Screening machine is removed. This first fraction has relatively large ones Particles on. The remaining good that has been screened for the first time, that by has passed through the first sieve body, then passes to a second Screen deck. Here is a second fraction with particles of somewhat smaller size severed. The individual screen decks are arranged one above the other. The Screening machine therefore has a certain vertical extension, the one appropriate room height of the company building is required. This is not always available.
Der Erfindung liegt die Aufgabe zugrunde, eine Siebmaschine anzugeben, die einen geringeren Bauraum nach oben erfordert, als dies bisher der Fall war.The invention has for its object to provide a screening machine requires a smaller installation space upwards than was previously the case.
Diese Aufgabe wird durch die Kennzeichen von Anspruch 1 gelöst. Der
Erfinder hat demgemäß erkannt, daß sich der Klassiervorgang mit Zerlegen
eines Gutes in mehrere Fraktionen auch dadurch durchführen läßt, daß man
einen Siebkörper in eine Anzahl von Ringsegmenten unterteilt, wobei die
einzelnen Ringsegmente voneinander abweichende Klassiereigenschaften
haben. Damit ist es möglich, auf einer begrenzten Zahl von Decks einen
mehrstufigen Klassiervorgang durchzuführen, bei dem zwei oder mehrere
Fraktionen anfallen.This object is solved by the features of

Die in Figur 1 gezeigte Siebmaschine weist ein Gehäuse 1 auf Dieses ist von
im wesentlichen zylindrischer Gestalt. Das Gehäuse 1 umschließt ein einziges
Siebdeck 2.1. Dieses umfaßt einen Siebkörper. Der Siebkörper ist derart
unterteilt, daß ein inneres Ringsegment 2.1.1 und ein äußeres Ringsegment
2.1.2 entsteht.The screening machine shown in Figure 1 has a
Unterhalb des Siebdecks 2.1 befindet sich ein Lochblech 2.2. Auf dem Lochblech liegen Bälle 2.2.3.A perforated plate 2.2 is located below the screen deck 2.1. On the Perforated sheet lie balls 2.2.3.
Die Maschine führt im Betrieb eine taumelnde oder kreiselnde Bewegung aus. Diese bewirkt das Bewegen des zu siebendes Gutes auf dem Siebkörper. Sie bewirkt zugleich ein Hüpfen und Klopfen der Bälle 2.2.3, die auf dem Lochblech 2.2 liegen, von unten gegen den Siebkörper des Siebdecks 2.1, und damit ein Losschlagen von Partikeln, die in den Maschen des Siebkörpers haften. The machine makes a wobbling or gyratory movement. This causes the material to be screened to move on the screen body. she causes the balls 2.2.3 which are on the Perforated plate 2.2 lie against the sieve body of the sieve deck 2.1 from below, and thus a loosening of particles that are in the mesh of the Screen body stick.
Die beiden Ringsegmente des Siebkörpers haben unterschiedliche Klassiereigenschaften. So hat beispielsweise das innere Ringsegment 2.1.1 des Siebkörpers 2.1 eine Maschenweite von 1,6 mm während das äußere Ringsegment eine Maschenweite von 2,2 mm aufweist.The two ring segments of the screen body have different ones Classifying properties. For example, the inner ring segment 2.1.1 the screen body 2.1 has a mesh size of 1.6 mm while the outer Ring segment has a mesh size of 2.2 mm.
Wie man aus Figur 1 ferner erkennt, steht auf dem Siebkörper 2.1 ein zylindrischer Stutzen 1.2. Dieser trennt das innere Ringsegment 2.1.1 vom äußeren Ringsegment 2.1.2 ab. Man erkennt ferner einen oberen Auslauf 1.3, einen mittleren Auslauf 1.4 sowie einen unteren Auslauf 1.5.As can also be seen from FIG. 1, there is a screen 2.1 cylindrical nozzle 1.2. This separates the inner ring segment 2.1.1 from the outer ring segment 2.1.2. An upper outlet 1.3 can also be seen, a middle outlet 1.4 and a lower outlet 1.5.
Der genannte Stutzen 1.2 weist eine Öffnung auf, die durch eine Klappe 1.2.1 absperrbar ist. Wie diese Klappe in Draufsicht aussieht, erkennt man - bei einer ähnlichen Ausführungsform einer erfindungsgemäßen Siebmaschine - aus Figur 2b.The mentioned nozzle 1.2 has an opening through a flap 1.2.1 is lockable. You can see how this flap looks in plan view - at a similar embodiment of a screening machine according to the invention - from Figure 2b.
Man erkennt ferner zwischen den Siebkörper 2.1 und Lochblech 2.2 einen Siebrahmen 2.3 und 2.4. Wie man sieht, ist an den inneren Siebrahmen eine Trennwand 2.5 angeschlossen. Diese hat die Gestalt eines Kegelstumpfes.One can also see one between the sieve body 2.1 and perforated plate 2.2 Screen frames 2.3 and 2.4. As you can see, there is one on the inner sieve frame Partition 2.5 connected. This has the shape of a truncated cone.
Die Vorrichtung arbeitet wie folgt:The device works as follows:
Von oben her wird in den Stutzen 1.2 zu siebendes Gut eingeführt. Es gelangt auf das Innensegment 2.1.1 des Siebkörpers 2.1. Partikel mit einem Durchmesser von bis zu 1,6 mm fallen hindurch und gelangen zum Auslauf 1.5. Größere Partikel hingegen wandern nach außen gegen den Innenrand des Stutzens 1.2. Durch die Öffnung mit der Klappe 1.2.1 gelangen sie schließlich auf das äußere Ringsegment 2.1.2. Diejenigen Partikel, die einen größeren Durchmesser als 2,2 mm haben treten durch den Auslaß 1.3 aus. Aus dem Auslaß 1.4 treten Partikel aus, die einen Durchmesser von zwischen 1,6 und 2,2 mm haben. Material to be screened is introduced into the nozzle 1.2 from above. It arrives on the inner segment 2.1.1 of the screen body 2.1. Particles with a Diameters of up to 1.6 mm fall through and reach the outlet 1.5. Larger particles, on the other hand, migrate outwards against the inner edge of the nozzle 1.2. You get through the opening with the flap 1.2.1 finally on the outer ring segment 2.1.2. Those particles that one have larger diameters than 2.2 mm through the outlet 1.3. Particles emerge from outlet 1.4, which have a diameter of between 1.6 and 2.2 mm.
Am Auslaß 1.5 treten schließlich jene Partikel aus, die einen Durchmesser von weniger als 1,6 mm haben.At the outlet 1.5 finally those particles emerge that have a diameter of have less than 1.6 mm.
Die Figuren 2a, 2b und 3 lassen Einzelheiten einer weiteren Ausführungsform erkennen. Auf dem Lochblech, auch "Prallboden" genannt, sind beispielsweise Kugeln angeordnet. Diese klopfen bei der Arbeit der Vorrichtung von unten gegen den Siebkörper und tragen damit zur Freihaltung der Sieböffnungen bei.Figures 2a, 2b and 3 leave details of another embodiment detect. On the perforated plate, also called "baffle plate", for example Balls arranged. These knock from below when the device is working against the sieve body and thus help to keep the sieve openings free at.
Die bereits erwähnte Klappe 1.2.1 ist im vorliegenden Falle steuerbar, so daß auf die Trennschärfe Einfluß genommen werden kann.The flap 1.2.1 already mentioned can be controlled in the present case, so that the selectivity can be influenced.
Stall zweier Siebsegmente kann ein Siebkörper auch in drei oder mehrere Siebsegmente unterteilt werden.Stall of two sieve segments can also be a sieve body in three or more Sieve segments are divided.
Die Figuren 4 und 5 veranschaulichen eine Taumelsiebmaschine, bei der ein einziges Siebdeck drei Ringsegmente 2.1.1, 2.1.2 und 2.1.3 aufweist. Die Ringsegmente sind wiederum durch zylindrische Trennwände unterteilt. Außerdem erkennt man Klappen 1.2.1, 1.2.2 und 1.2.3.Figures 4 and 5 illustrate a tumbler screen in which a single screen deck has three ring segments 2.1.1, 2.1.2 and 2.1.3. The Ring segments are in turn divided by cylindrical partitions. You can also see flaps 1.2.1, 1.2.2 and 1.2.3.
Hierbei wird das zu klassierende Gut auf die zentrale Siebscheibe 2.1.1 aufgegeben. Diese zentrale Siebscheibe hat eine feine Maschenweite. Im Zuge der Taumelbewegung fallen die feinen Bestandteile durch die Maschen hindurch. Die gröberen wandern durch die Öffnung an der Klappe 1.2.1 zum Ringsegment 2.1.2, das eine mittlere Maschenweite hat. Was auf dem Ringsegment 2.1.2 liegenbleibt, gelangt durch die Öffnung an der Klappe 1.2.2 zum äußeren Ringsegment 2.1.3.Here, the material to be classified is placed on the central screen 2.1.1 given up. This central screen disc has a fine mesh size. in the In the course of the tumbling movement, the fine components fall through the mesh through it. The coarser migrate through the opening in the flap 1.2.1 to Ring segment 2.1.2, which has an average mesh size. What on that Ring segment 2.1.2 remains, passes through the opening in the flap 1.2.2 to the outer ring segment 2.1.3.
Die in Figur 6 dargestellte Ausführungsform weist wiederum ein unterteiltes Siebdeck auf. Es umfaßt eine mittlere, zentrale, kreisförmige Siebscheibe 10.1.1 feiner Maschenweite. Diese zentrale Siebscheibe 10.1.1 ist umgeben von einer zylindrischen Trennwand 10.2. Man erkennt eine Klappe 10.2.1, die während des Betriebes steuerbar sein kann. Dasjenige Gut, das nicht durch die feinen Maschen der zentralen Siebscheibe hindurchgefallen ist, tritt durch die Öffnung an der Klappe 10.2.1 aus und gelangt auf die Ringsegmenthälfte 10.1.2, die eine mittlere Maschenweite hat. Was hier nicht durchfällt, gelangt auf die weitere Ringsegmenthälfte 10.1.3 mit einer groben Maschenweite. Was übrigbleibt, tritt durch einen Auslaß 10.5 aus.The embodiment shown in Figure 6 again has a subdivided Sieve deck on. It comprises a central, central, circular sieve disc 10.1.1 fine mesh size. This central screen disk 10.1.1 is surrounded from a cylindrical partition 10.2. One recognizes a flap 10.2.1 that can be controllable during operation. That good that is not through the fine mesh of the central sieve disc has fallen through the opening on the flap 10.2.1 and reaches the ring segment half 10.1.2, which has an average mesh size. What does not fail here comes on the further ring segment half 10.1.3 with a coarse mesh size. What remains, exits through an outlet 10.5.
Wie man sieht, kann ein Siebdeck gemäß der Erfindung somit in geschlossene Ringsegmente unterteilt werden. Es kann aber auch das einzelne Ringsegment nochmals unterteilt sein, so wie bei der Ausführungsform gemäß Figur 6.As can be seen, a screen deck according to the invention can thus be in closed ring segments can be divided. But it can also do that individual ring segment can be subdivided again, as with the Embodiment according to FIG. 6.
Ein ganz entscheidender Vorteil der Erfindung ist in jedem Falle der folgende: Es ist nicht notwendig, mehrere Siebdecks übereinander zu türmen. Hierdurch werden die Kippkräfte in geringen Grenzen gehalten. Außerdem liegen grobe Verunreinigungen häufig nur in geringer Menge vor. Beim Stande der Technik muß dennoch ein komplettes Siebdeck für diese groben Verunreinigungen verwendet werden. Wendet man die Erfindung an, so läßt sich alles in einem einzigen Siebdeck ausführen, oder es läßt sich zumindest die Zahl der Siebdecks begrenzen.A very decisive advantage of the invention is in any case the following: It is not necessary to stack several screen decks one above the other. Hereby the tipping forces are kept to a minimum. In addition, there are rough ones Impurities are often present only in small quantities. In the state of the art must still have a complete screen deck for these coarse contaminants be used. Applying the invention, everything can be combined in one run single screen deck, or at least the number of Limit sieve decks.
